Endress+ Hauser Australia introduce the Prowirl 73 stand-alone, multivariable vortex flowmeters for measuring mass flow, energy, density, temperature and volumetric flow of liquids, gases and steam. Unlike most vortex flow meters, the Prowirl 73 features an integrated temperature sensor and inbuilt flow computer. This reduces the requirement for additional devices and enables these flowmeters to simultaneously measure temperature and calculate mass flow for accurate energy management in facilities or processes.

Prowirl 73 vortex flowmeters greatly simplify mass flow and energy measurement of technical and natural gases and offers a cost effective alternative to other gas mass flow sensors. External pressure values can be read in digitally on the flowmeters with high accuracy via HART and the inbuilt flow computer uses pre-programmed compressibility data to calculate the mass flow, with AGA natural gas equations to additionally report energy content. Currently, 18 technical gases and compounds of up to eight combinations of those gases are included. This wide range of pre-programmed gases significantly simplifies the setup procedure, to ensure accurate gas mass flow calculations.

Reliability of Prowirl 73 vortex flowmeters is enhanced thanks to the patented DSC sensor. This sensor is mechanically balanced making it immune to pipe vibration and capable of withstanding temperature shocks over 150 K/s. Its aperture free design eliminates the risk of clogging from particles transported in the medium.
